To all whom it may concern:

Be it known that I, ALExANDER WINTON,

a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Pressure-Governors for Explosive-Engines, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to limprovements in pressure governors for explosive engines, and the object is to cause the governin pressure to be formed in and taken from t e engine cylinder.

In the accompanying drawings, Figure 1, is a sectional view of an explosive engine showing the preferred form of this invention applied thereto. Fig. 2, is a similar'view showing one modified form with which vthe generic invention may be embodied. Fig. 3, 1s a similar view of another modified form in which the generic invention may be embodied. Fig. 4, is an enlarged detached sectional v'iew of the reducing and regulating valve shown in the preferred form illustrated in Fig. 1. Fig. 5, is an enlarged detailed view of the check valve used between the engine cylinder and the point at which the pressure from the cylinder performs its functlon in controlling the explosive inletvalve of the engine. Fig. 6 is an end' elevation of a plurality of cylinders, showing my invention applied thereto.

In carrying out thisinvention, cylinder 1 is provided with a suitable exp osive inlet passage way or chamber 2 which communicates with the explosive inlet passage 3. The explosive mixture is drawn y the action of the engine piston 4 through the inlet passage-ways into the cylinder 1 and there com ressed before its explosion, in a manner Well `understood by those skilled in the art, and which needs no further explanation.

An explosive inlet valve 5 controls the inlet passage-ways to the envine cylinder, and according to its amounto movement from .ts seat, controls the amount of explosive zharge, and thereby the power and speed of Jhe engine, which is also well lunderstood by ahose sln'lled in the art. Invthe present in Specification of Letters Patent. Application filed August 17, 1904.

vention, the movement of the inlet valve 5 to regulate the size of the charge to the engine cylinder, is controlled by means of pressure which is formed in the engine cylinder. In the form here shown, the inlet valve 5 has its stem 6 extending into a pressure-receiving chamber 7, and carries a piston or diaphragm 8, thus providing the explosive inlet valve 5 with a pressure-actuated member.

9 is an exhaust valve which may be operated in any desired manner, and as it forms no part of the present invention, need not be further described,V as its function is well un- I will first describe the preferred construction which is shown in Fig. 1, and in which a pipe 10 is in communication with the interior of the engine cylinder l1 at a point preferably slightly inside of the outward limited movement of the piston 4. The pipe 10 also communicates with a suitable receiving chamber 11, and the pipe is provided with a check valve or valves. As here shown, two check valves 12 and 14 are used, one being located 4adjacent the engine cylinder, and the other adj aicentv the receiver. The receiver is in communication with the chamber 7, so that the pressure therein may act upon the pressure-actuated member 8 for controlling the movement of the inlet valve 5., As shown in Fig. 1, this communication consists of a pipe 15 which communicates with the receiver, and also with a reducing and regulating valve 16, and the said valve 16 is in communication with the chamber 7 which contains the pressure-actuated member 8. A relief valve 18 is in communication with the pipe 17 and a pressure relief button 19 is in communication with the pipe 17 through the medium of asuitable pipe 20.

Thisfinvention is especially intended for use in connection with explosion engines for In operation, when the passage-way 21 is uncrvered by the engine piston, pressure passes from the cylinder to the pressure-actuated member 8, and thereby tends to hold the explosive inlet valve 5 closed, and the pressure will be sufficiently great to prevent the operation of the motor unless some relief is provided. Through the upon the button 19 will still further relieve the pressure from the ressure-actuated member 8, according to t e amount of its downward movement, and thus regulate the speed and power of the motor, according to the requirements in driving the vehicle. The receiver 11 and the reducing and regulating valve 16 sL-rve to make the pressureV more uniform, though these are not absolutely essential to the working of the invention, and may be omitted as shown in Fig. 2. If desired, the pressure can also be utilized for effecting a forced lubrication by providing a communication with the tank containing lubricating oil and the pressure passageway.` As shown in Fig. 1, a pipe 22 establishes communication between the receiver 11 and the reducing and regulating valve 23, and a pipe 24 will establish communication between the said valve 23 and a lubricating oil tank not here shown.

Where a multiple cylinder motor is used, there will be a plurality of pipes 10, one of which will run to each engine cylinder, and the'lower end of the pipe 17 will be provided with branches communicating respectively with the pressure chamber of the respective engines, and thus control the pressure-actuated member 8 of the respective engines. In this latter event, the pressure relief valves 18 and 19 will be common to each engine which constitutes the motor, so that they will control all the engines alike.

Fig. 2.operates in the same manner as Fig. 1, and diers therefrom only in the omission of the receiver and the regulating valves 16 and 23.

Fig. 3 omits the receiver and the regulating valves 16l and 23, and substitutes for the relief valve 19 a controlling valve 25 located directly in the pipe line 17, and substitutes for the relief va ve 18 a vent opening 26 located between the valve 25 and the pressure-actuated member S. The operation of this modification is, that when the valve 25 is closed, the explosive inlet valve 5 has a free movement, because of the vent 26, and the engine'will run its maximum speed and power. When the valve 25 is opened, pressure passes through the line 17 to the pressure-actuated member 8 and controls the movement of the valve corresponding to the amount of pressure permitted to pass thereto. The two systems differ in that the irst two speeds the motor when the relief valves are opened, andthe latter s eeds the motor When the air valve 25 is c osed. In both systems, however, the motor is controlled through the medium of pressure produced in and taken from the motor or engine cylinder.

From the foregoing disclosure and description, it will be observed, that the piston suction exerts an opening pressure on the inlet valve 5, while a portion of the explosive expansion within the explosion cylinder acts to close the said inlet valve in other words, the engine speed and power is controlled by utilizing the explosion expansion in opposition to the suction action.

The mechanism for carrying into effect the generic invention herein described, may be varied from that disclosed without departing from the spirit and scope of the invention.

Having thus described myinvention, what I claim and desire to secure by Letters Patent, is

1. A controlling mechanism for explosion engines, comprising the combination of an explosion cylinder, a piston therein, the cylin er having an explosive inlet communication and a valve controlled exhaust opening, a valve for said inlet opening inwardly under the suction of the piston, a ressure actuated member connected with tlie inlet valve to kee it closed, a communication between the exp osion cylinder and said ressure actuated member independent of t ie cylinder exhaust, whereby the explosion ex ansion exerts a pressure upon the inlet va ve in opposition to the opening suction action thereon of the cylinder piston, and a pressure escape for said communication.

2.
